...Fiber and its function in our bodies 10/09/2011 Fiber is important when it comes to our body and our daily diet. We need to make sure that we consume a certain amount of foods in each food group. We also need to make sure that we get our daily vitamins, fiber and many other nutrients on a daily basis. Dietary fiber adds bulkiness to our diet. It makes you feel full sooner; it can be supportive in controlling our weight. Fiber aids digestion, helps prevent constipation, and is used for the treatment of diverticulitis, diabetes, and heart disease. The main function of fiber though, is to regulate digestion in our bodies. Soluble and insoluble fibers are a little different; they both supply imperative elements that keep you making a healthy lifestyle. When we talk about insoluble fiber, this fiber does not dissolve in liquid. Its task is to keep the digestive tract free of anything that might cause a blockage in your body. It will absorb liquid and expand in the tract, successfully speeding your process of moving bulk through the tract while scraping the interior walls clean of any residue. Then there is soluble fiber, which attracts water and form a gel that slows the digestive process down. It postpones your stomach from emptying and makes you feel full longer. This helps us control our weight and over eating. When your stomach is slower at emptying, it may affect our blood sugar levels. This can have a beneficial effect on our insulin sensitivity, which can help control...

...Fiber Michelle Martinez SCI/220 November 9, 2013 Professor Hatton Fiber #2 Tell me about fiber. Fiber is a nutrient known as roughage needed to help digest food. Fiber can be found in fruits, vegetables, and whole grains. Fiber should be part of our diet in order to keep our digestive system regular and healthy. Fiber isn't digested by your body. Instead, it passes relatively intact through your stomach, small intestine, and colon and out of your body (Dietary Fiber: Essential for a Health Diet, 2013). Lack of fiber can bring discomfort and health issues. What are the benefits of fiber and the problems with a low-fiber diet which include problems outside of the GI tract? Benefits of a high fiber diet for example are 1) Fiber keeps the body regular, helps pass stool easier, prevents constipation, and solidifies the stool because fiber absorbs water and adds bulk to the stool 2) Fiber can lower cholesterols levels such as beans, oats, and flaxseeds which are soluble fiber and may lower blood cholesterol levels by lowering bad cholesterol 3) Fiber maintains bowel health because fiber ferments in the colon and can help prevent hemorrhoids and diverticular diseases 4) Fiber can aid with weight loss because high fiber food need to be chewed more, which gives the body time to absorb and can make you feel full. (Dietary Fiber: Essential for a Health Diet, 2013) The reason people have to limit their fiber intake due surgery, inflammatory disease, or narrowing of the...

...Unit 8. Lab 1. Fiber Optic Connector Assembly The most critical part, the Cable and Fiber Preparation where the fiber is mounted, is the ferrule. The Ferrule is a long, thin cylinder with the fiber mounted in the center hole. The center hole is sized to match fiber's cladding diameter which is usually 125um. When fiber connector ferrules are made from several types of materials including ceramic(Zirconia), stainless steel and plastic. The ferrule's job is to center and align the fiber and protects it from mechanical damage. The end of fiber is at the end of the ferrule, where the fiber end is polished smooth either flat or with a curvature. The ferrule is mounted in the connector body and then the connector body is attached to the fiber optic cable structure. Finally, a strain-relief rubber boot protects the connector-cable junction. Fiber optic connectors usually do not have the male-female polarity. Most fiber connectors are male only. Instead, fiber connectors mate to each other in fiber adapters, which are often called mating sleeves or coupling receptacles. Fiber optic adapters used to mate different connector types such as a FC connector to a SC connector are called hybrid adapters. Although this approach requires the use of separate adapters, it otherwise reduces fiber connector inventory requirements since now you need to stock one type of connector only. Another advantage is that fiber adapters can be designed to mate one type of connector to another, which is a big...

...Question #3: In what respects did the use of fiber evidence in the Wayne Williams trial differ significantly from its use in previous cases? Numerous criminal trials over the years have used fiber evidence. In 1936, the wife of a NBC executive was murdered and the killer caught partly due to fibers from twine used to bind her during the murder. Ted Bundy was convicted of the murder of a 12-year old girl partly due to fibers found in his van. The trial of Wayne Williams, also based on fiber evidence, differed from other cases in several significant ways. From July 1979 to May 1981, thirty black children and young men were reported missing or found dead in the area of Atlanta, Georgia. The Georgia State Crime Lab found yellow-green nylon fibers and violet acetate fibers on the bodies and clothing of victims. The fibers from the different victims were generally similar to each other, linking them to a single source and tying them to one killer. The Wayne Williams case was the first time fiber evidence played a significant role in a case involving a large number of murder victims. An Atlanta newspaper wrote an article about several different fibers being located on the bodies. After the article, bodies located in the Atlanta area rivers were nude or clothed only in underwear. The release of the information caused a change in the way the suspect disposed of bodies, in an apparent effort to eliminate fiber evidence. Media attention appeared to result in a change in pattern of...

...Fats and Fibers Ewanshia J. Graham SCI/241 - Nutrition September 13, 2012 Derrick King Fats and Fibers According to the American Heart Association (2010) there are a number of fats that are consumed by humans on a daily basis; some fats are beneficial for us while others are not. The four major dietary fats, that we normally consume, have varying chemical structures and differ in their effects on the body. Saturated and transfer fats are considered harmful and have the potential to cause high levels of cholesterol and heart disease. On the opposite end, monounsaturated and polyunsaturated fats, in moderation, are good for the body and provide needed energy for vital bodily functions. The composition of each type of fat contributes to its’ influence on the body. For instance, saturated fats are named due to the presence of hydrogen atoms that completely cover the molecule. These hydrogen atoms cause saturated fat to solidify at room temperature and are contained in foods such as cheese, butter, cream, chocolate, coconut oil, and cottonseed oil. These fats tend to be larger and harder for the body to breakdown. Unsaturated fats contain at least one double bond within the fatty acid chain with the formal name depending on how many double bonds are present; trans fats are included under the label of unsaturated fats as well. Trans-fatty acids are harmful because they can raise your low-density lipoprotein (LDL) levels while lowering your high-density lipoprotein...

...look into the studies on fiber we find that fiber is important for gastrointestinal health as well as cholesterol-lowering benefits. Fiber is mainly used by your body to clean it out easier. It passes through your body unchanged and will push everything in front of it in the digestive system along, making the digestive process easier. Another function for fiber is to regulate how full you are. The amount of fiber you eat is what gives you the full feeling when you eat a lot. Some of the places you can find fiber is in oats, wheat and basically any food with any part of a plant in it. Fiber is a plant that cannot be broken down by the human digestive system. Intestinal bacteria are able to utilize fiber as nutrition, thus helping you to be well. Our digestive system is unable to break down dietary fiber and this indigestible ingredient has many effects on the functions of the body. Because fiber is not absorbed by the body, it does not significantly increase the energy content of food, and thus helps you to control your body weight. Soluble fiber is “soluble” in water. When mixed with water it forms and swells into a gel-like substance making the feces increase in weight. The dissolving of some fibers in water forms viscous solutions in the intestines; these are called viscous or soluble fibers. Soluble fiber has a lot of many benefits, including but not limited to, moderating blood glucose levels and lowering cholesterol. Some of the soluble fibers include pectins, gums, mucilages...

...com/anatomy/muscular-male#full-description The muscular system is responsible for the movement of the human body. Attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a person’s body weight. Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves. Muscle tissue is also found inside of the heart, digestive organs, and blood vessels. In these organs, muscles serve to move substances throughout the body.... Muscular System Anatomy Muscle Types There are three types of muscle tissue: Visceral, cardiac, and skeletal. 1. Visceral Muscle. Visceral muscle is found inside of organs like the stomach, intestines, and blood vessels. The weakest of all muscle tissues, visceral muscle makes organs contract to move substances through the organ. Because visceral muscle is controlled by the unconscious part of the brain, it is known as involuntary muscle—it cannot be directly controlled by the conscious mind. The term “smooth muscle” is often used to describe visceral muscle because it has a very smooth, uniform appearance when viewed under a microscope. This smooth appearance starkly contrasts with the banded appearance of cardiac and skeletal muscles. 2. Cardiac Muscle. Found only in the heart, cardiac muscle is responsible for pumping blood throughout the body. Cardiac muscle tissue cannot be controlled consciously, so it is an involuntary muscle. While hormones and signals...

...human body energy and they have 9 calories per gram, but some fats are better than others. At one time all fats were considered to be bad and cause all types of health problems from cardiovascular to diabetes. Now after some years of research we have learned that not all fats are bad. A good fat is an unsaturated fat and it helps fight diseases that people use to think fats caused. Unsaturated fats are made up of two parts, monounsaturated, and polyunsaturated fat. These two types of fats have beneficial effects on cholesterol levels. Bad fats are saturated fats that clog arteries. These fats are known to come from meat and dairy products. The difference between saturated and unsaturated fat is that even though they are both in a variety of foods that we eat, they have different effects on our body. Saturated fats can be detrimental to a person’s heart and cholesterol, where unsaturated fats can be beneficial to your heart. Trans-fats are created through the process hydrogenation of plant- based oils and animal fats like shortening or margarine. Trans-fatty acids are harmful because of the hydrogenated oils in foods. Any oil that is hydrogenated is poison and very toxic to the liver. Trans-fatty acids cause a body a lot of problems like inflammation, and can cause a person to age faster. Once trans-fats are absorbed within the circulation it tends to get stiff and hard, leading to atherosclerosis. The function of fiber and lipids...

...saturated fatty acids. They can be found in foods that contain cheese, lard, or butter. Unsaturated fats are fat acids that contain double bonded chemicals that eliminate hydrogen atoms. Trans – fatty acids are usually found in man made products. They are created in an industrial process that’s adds hydrogen to liquid vegetable oils to make them solid. This type of fat can be found in most fast food products. Hydrogenated fats are found in margarine and vegetable shortenings. They are created by the forcing of hydrogen into liquid oil. They are mostly used in processed foods such as baked goods. Fiber and lipids serve two separate functions that both help keep the body healthy. Fiber absorbs cholesterol and helps to slow the amount of glucose the body absorbs. Fiber helps collect waste and build it into one entity rather than the body having diarrhea and waste just running through the body. It allows the waste to form into a single...

...Take a look at society and the food's people eat. Are the amounts he or she consumes too much or too little? Or is the right amount of nutrients obtained daily from each’s meals. Many do not understand how important it is to manage his or her diet with the proper nutrients and portion sizes. Nutrient is a vital part of everyday functions and without it the body is more vulnerable to disease. In this paper, it will show my nutritional intake for a span of three days. In those three day, it will show the proteins, carbohydrates, and lipids that held nutritional value in my daily meals. It will also explain my macronutrients intake ranges, fiber intake range, and the importance both hold when properly maintained. Last I will discuss dietary modification I can make to better improve my health or stay healthy. The recorded times will assist with changing my views of what a healthy lifestyle is, and how to achieve it through a variety of food groups. The "I Profile" (2014) showed through the three day span the Proteins, carbohydrates and lipids were obtained in all my meals but were all below intake range levels when compared to Dri. My total consumption of proteins came up to be 69 grams and was consumed mostly from dinner and lunch. The Double whooper I had from burger king was the largest factor that lead to 69grams of protein, it contained 28 percent alone. The Big mac and twenty piece chicken nuggets for lunch amounted to 36 percent of the sixty-nine grams and last the...

...Understanding Your Fats and Fiber Lori Siegele SCI/241 Nutrition May 23, 2013 Denice Mittelstaedt Understanding Your Fats and Fiber Understanding Your Fats and Fibers Lori Siegele May 23, 2013 SCI/241 Nutrition Denice Mettelsteadt According to “Face the Fats” the bad fats are the saturated and the Trans fats, better fats are the monsaturates and the polyunsaturated fats, and the best facts are the omega-3s. (B, 2012). There have been so many illness that are blamed on fats, I don’t think there is one out there that hasn’t been, from heart disease to cancer. The bad fats have got to be limited and when you are putting them in your body you want to make sure that you are staying with the low percent. The good fats you want to make sure that you are staying on the higher percent. So in other words the bad fats have got to be 5 % and lower and the better/best fats need to be 20 % and higher. A Saturated fat is known as a fat that is a type of single-bond animal or vegetable fat. (These are mostly found in butter, meat, egg yolks, and coconut or palm oil) it is known to increase the cholesterol level in the blood. A fat having a chain of unsaturated fatty acid is known as a unsaturated fat. Trans-fatty acids are known as an unsaturated fatty acid formed by partial hydrogenation of vegetable oil that is also believed to raise the blood cholesterol levels in the body. The differences in the stability between saturated and unsaturated fats are known as hydrogenated...

...it breaks down the ingredients of my diet and shows me exactly what it is that I am putting into my body on any given day. In addition, since starting this journal I feel that it is important to be aware of what I am eating and I plan to continue to use this journal in the future. Not only does the journal allow me to record my daily diet but it also shows me the recommended daily values for each of the food groups, minerals, and vitamins based on my age, height, and body weight. Understanding what is being put into my body is essential for living a long, healthy life. I tried to eat a wider variety of foods over the course of the three days so that I could have a balanced diet to write about. Out of the foods that I included in my diet, only a few foods contained protein, carbohydrates, and lipids. The protein in my diet was attributed to the chicken and the green vegetables that I consumed over the three days. The carbohydrates in my diet were mainly from the bread and the pizza that I consumed over the three days. The lipids that I consumed over the three days were from the fatty foods that I ate, such as fish, bacon, and pizza. Lipids come from the fats and oils that are in my diet (Carter). According to the Dietary Recommenced Intake, I had exactly 100% of the DRI for protein-carbohydrate-fat intake, which I was happy to see. However, my protein intake based on body weight was 370%, which was high. I feel that the protein in each of the foods I ate was overall at a...

...interactions. (Medical News Today) Where do carbohydrates come from? Carbohydrates can be found in fruits, vegetables, breads, cereals, and other grains, milk and milk products and foods containing added sugars (e.g., cakes, cookies, and sugar-sweetened beverages). Healthier foods higher in carbohydrates include ones that provide dietary fiber and whole grains as well as those without added sugars. Foods higher in carbohydrates such as sodas and candies that also contain added sugars are the ones that add extra calories but not many nutrients to your diet. (CDC) How do carbohydrates work in the body? The goal of digestion is to break down carbohydrates into small molecules the body can absorb. The human body contains the digestive enzymes to break down starch into disaccharides and disaccharides into monosaccharides. The final products of carbohydrate digestion are the monosac¬charides. The monosaccharides are absorbed by the small intestine and released into the blood stream. Then they are carried by the blood to the liver, where fructose and ga¬lactose are converted into glucose. Glucose is the primary monosaccharide used by the body for energy....

...Three Day Intake Ashley Griggs SCI 220 June 20th, 2016 Sriya Krishnamoorthy Three Day Intake I recorded my meal intake for three days using Iprofile Mobile, through WileyPLUS. I was able to analyze and see the foods I consumed broken down into nutritional values. This project was about assessing and evaluating our food intake and what things can and can’t be modified to live a healthy lifestyle. This paper focuses on protein, carbs, and lipid and fiber intakes. Also, how my diet can be adjusted to be healthier and more nutritional. The foods that provided protein on all three days was Eggs, Bacon, orange juice, soft tacos. Watermelon, milk, banana, waffles, McChicken, Chicken breast, broccoli, crispy rice, apple, and steak, and loaded mashed potatoes. The foods that contained carbs was the same and my sweet teas, and sodas which I had all three days. All of my foods have lipids. Based on my food journal I took in 16%, 20%, and 26% of protein. All days was acceptable between 10%-55% is the recommended amount. The Carbohydrates I took in was 58% on day one, 62% on day two, and 48% on day three. Again, all these is in the acceptable range for my DRI, which is 45-65%. My lipid intake was 19%, 21%, 27%. My first day was below average for my DRI, which scaled between 20-35%. If going by my DRI; the three days I ate and recorded I was in a good range for my macronutrients. If I would have eaten more fast food, and less home cooked meals I would have seen a huge difference in my...

...Week 3 CheckPoint Fiber Research Week 3 CheckPoint Fiber Research Phoenix University SCI 241 The role that fiber plays in a human body, is that it’s the main function in the body is to regulate a person’s digestion. Some examples of food sources for fiber can be found in bread, pasta, flax and seed. Researches have also found out that most yogurts now have a fiber additive, so most yogurts can be added to good food sources for fiber. The difference between soluble and insoluble fiber is that soluble fiber is soluble in water, while insoluble fiber does not absorb or even dissolve in water. When you mix soluble fiber with water, the water and fiber turns into gel. The benefit of soluble fiber includes lowering a person’s cholesterol as well as moderating a person’s glucose levels. You can find soluble fiber in oats, oatmeal, peas, beans, lentils, barley, fruits and vegetables. Insoluble fiber passes through the body’s digestive system. The benefits that insoluble offers include intestinal health of a reduction in the risk of occurrence of colorectal cancer, hemorrhoids, and constipation. Insoluble primarily come from bran layers of cereal grains. The fiber recommendations for adults are 20-35 grams per day for adults, or 10-13 grams for every 1,000 calories in one’s diet. The fiber recommendation for children really depends on their age. Kids ages 4-18 need to have an intake of 25-38 grams per day. For adults it’s recommended that the amount of an adult should come...
